My fault. That was good, "hot date" and "an attic." Pretty funny.

OP, I can't make where that yellow wire is coming from. If you can trace it back to it's origin then I can help you. If it's from the fan than it goes on the capacitor with the red wire on the common terminal.

The yellow wire in my pic is the low voltage (24 v) going to the coil.

Today as I was trying to find a cap. I came across a place that worked on motors in the next town. I stopped. No luck on the dual cap. I suggested maybe two seperate cap if he had them. He had a 40 and 3 for 16.00. For some reason I had him check my old one. A place right down the road from him told me it was weak and needed replaced. This guy checks it and it checks out right on the money. Now we are back to the fan.

Got the fan replaced with its own cap. The new motor is 1/5 hp. Old one was 1/6 hp. Old moter was 1100 rpm's, new one is 1075. The change in motors meant a change in uf form 3 to 5 for the fan, so it got its own cap.

The old cap was 440 volts. The compressor is still running off of it. The new cap for the new fan motor is 370 volts/5 uf.

Long story short, for $157 and change my house is cool again.

Hopefully, in my wife's eyes, I will be when she gets back from Gulf Shores.

]So, you kept the dual capacitor (440V) connected to the compressor and installed the new motor with the new cap (370V) right?[/B]
If you changed the dual capacitor (440v) for 370V you're doing wrong.

Just making sure

Right new 370 cap for the new fan motor. I did ask the young guy about that. He was a different guy than I first talked to. His opinion was the fan was only 220 volts and the new cap would be okay. The new fan does seem to work fine. Starts with no hesitation.

Looks like the original fan was rated for 5 mfds. It was running off a 3 mfds cap. I was not aware the original fan was rated for 5uf's.

I am very inexperienced with this sort of thing. I did work on the older kitchen appliances several years ago, never really got into heating and air much. That being said, I take "mfd" to be the same as uf (micro farads). Hope I spelt that right.
